A special version of the MTS3000-Restan system can be used to determine residual stress in plastic and polymeric materials by the hole-drilling method.
The MTS3000-Restan system is actually the only system in the world specifically designed to carry out these tests, thanks to a modification of the standard drilling technology.
Drilling is done at very low speed (lower than 50RPM) in order not to generate local heat in the material. It also use a reduced feed speed to minimize the effect of drilling (approx. 0.1 mm/min).
